I have the htc thunderbolt on verizon, have all new updates, phone works great. Unless... When i put the phone in the car dock. I will lose all audio including key tones, ringtones, music, basically all audio from phones internal speaker. It acts like it is in silent mode. No matter what volume position. When i remove from the dock, it still will not activate audio, i have to restart the phone for audio to work. Sometimes the audio quits right away amd sometimes it will stay on up to 20 min before going silent while in the dock. Any suggestions from anyone?
